Many ancient Bitcoin addresses have long been acquired by market makers or associated as concerted actors.

In the past, when writing articles, I could still see some posts on early 4Chain and Reddit forums about acquiring ancient Bitcoin addresses from before 2013.

In May 2020, messages collectively signed by 145 'vintage' Bitcoin addresses (created between 2009-2010) appeared on the blockchain, stating: Craig Steven Wright is a fraud and a scammer.

This indicates that there have been hundreds of events involving ancient addresses in the Bitcoin community acting as concerted actors.

Some miners have privately mentioned that entities like Wall Street consortiums, exchanges, market makers, and fund managers have approached early large mining operators as aligned interests. At critical moments of market changes, mining operators move addresses to coordinate trading.

Therefore, Weibo believes:

The unusual activity of 80,000 BTC ancient addresses is intentionally made visible to the market by market makers, thus affecting market sentiment and price fluctuations, in line with market manipulation.

Even if someone genuinely wants to sell 80,000 BTC, it can completely be done through over-the-counter transactions, with no need for a massive market dump.
